TDK-Lambda is introducing its CPFE500 range of baseplate-cooled power supplies for outdoor applications such as broadcast, LED signage and COTS military.

The AC/DC power supplies are capable of providing 500W without the need for fan cooling and have a temperature range of -40 to +85C.

They are available with protective coating to shield against the ingress of dust, moisture and other contaminants.

Since there is no fan, the CPFE500 series is also suited to low audible noise applications, such as audio mixing desks and recording studios.

All models in the CPFE500 range are delivered with TDK-Lambda’s three-year warranty and meet EN55022/EN55011 Class B and MIL STD 461/462D CE102 EMC specifications.

These single output power supplies are available in 12V, 28V or 48V DC versions.

Up to +/-20 per cent output voltage adjustment is possible, enabling the CPFE500 to be used in a variety of customer-specific bulk-power applications.

The CPFE500 has a lightning surge capability up to 6kV.

Efficiency of up to 88 per cent ensures heat dissipation is minimised.

Operating from a universal input of 85 to 265V AC with PFC, the CPFE500 can operate both in series or parallel with built in O-ring diode and active current share as standard.

A power-on signal, remote on/off and remote sense are included.
